I picked up a set of Primacy MXV4 91H. They seem to be heavily susceptible to tramlining. I can't really speak for impact on range since it's starting to warm up here. I noticed a roughly -0.2 miles/kWh change immediately with tire pressure at 33psi (this is what the tire shop set it at). Now that I'm at 47psi, I'm getting +0.2 mile/kWh compared to my Ecopias at 50psi, so who knows. I think there are other factors in play here other than tire (mainly temperature changes) that could be causing the fluctuations in efficiency. I also noticed that while it was both under and overinflated, the responsiveness was not acceptable (pothole avoidance left much to be desired, very loose mushy response)- but now that the tires have a few hundred miles on them, I'm noticing a drastic improvement. This tire is superior to the Ecopia's in nearly every category. Traction (including snow traction) and ride are both excellent. If I could do it over again, I would get the V rating for better grip, but I'm happy with the H rating. It's a great tire overall.

All I can say about the Defender is that I'm so glad Michelin has a 30-day satisfaction guarantee! I took a huge hit to range. It felt like I was driving through mud. Slowing on a decline = not good.

I swapped them out for the Primacy MXV4 and now it's much better!

The Defenders are definitely not as good LRR as the others. It was also discussed in the PriusChat Forum.

Just got a Leaf 2014SV and I'm impress with the torque (coming from a Prius!). The car as already 12000 miles, I guess I'll need to keep an eye on the tires. The MXV4 seems a good choice, but TomT is the only one telling he didn't see much decrease in range. Why ?

I used them, they killed my range big time compared to my Ecopias. I could also fee a big drop in my acceleration performance.

After two sets of the OEM tires that lasted around 12,000 miles each I've just about worn out my Michelin Primacy MXV4s after 25,000 miles. I enjoy tossing the Leaf around in the corners and am wondering if anyone has run the Michelin Pilot Sport A/S 3 and if so what they thought of them.

My wife's Lexus IS250 just got Michelin Pilot Sport A/S 3. Awesome tire. Handling is great. Noise is only noticeable on bigger road bumps but strangely enough, quieter on the smaller bumps and on the concrete grooves on the highway here in California. Haven't had a chance to try in rain but is highly rated on Tire Rack. The ride on IS250 is fairly stiff already but these tires softens the ride a little. The review on Tire Rack have this Michelin behaves more like a summer tire instead of ultra high performance (UHP) all season tire.

Motor Trend magazine has a video on Youtube showing that Nissan Leaf's performance can be enhanced by changing the type of tires.

My main concern with this type of tire is loss of range since UHP tires would have more grip on the road.

I still have the original tire on LEAF but looking at Continental PureContact with Ecoplus.

My original Bridgestone EP422 tires on the front of my 2015 Leaf are about 4/32" after 32k miles- rear tires have plenty of tread left. Thinking of getting the Michelin Primacy MXV4. But I saw the Primacy MXM4 (newer model tire I believe), and wondered if any one had some feedback, opinion, or info on these. Thanks, Kip.........
